[vcf-midatlantic] OK seriously, how rare is the real 1541-II drive?

[Bill Degnan]

Now I wonder, compared with other CBM drives, is there a rarity ranking?

I am thinking some of the rarest 8-bit CBM drives manufactured by CBM are
(in no particular order and without looking on the internet for the answer)

8080 (dual 8" IEEE drive)
1540
1551
9060
9090
1570 (where these actually sold)
The drive that came with the C-65

am I missing anything rarer than these?

Next would be
2040 (IEEE)
4040 (IEEE)
8250 (IEEE)
SFD-1001
